Question

I have a store with a list of items. When my app first loads, I need to deserialize the items, as in create some in-memory objects based on the items. The items are stored in my

Answer 1

Select effect does not help us if we in a callback functions, when code flow is not handled by Saga. In this case just pass dispatch and getState to root saga:

store.runSaga(rootSaga, store.dispatch, store.getState)

And the pass parameters to child sagas

export default function* root(dispatch, getState) { yield all([ fork(loginFlow, dispatch, getState), ]) }

And then in watch methods

export default function* watchSomething(dispatch, getState) ...

Answer 2

you can use select effect

import {select, ...} from 'redux-saga/effects'

function* deserialize( action ) {
    const state = yield select();
    ....
    yield put({ type: 'DESERIALIZE_COMPLETE' });
}

also you can use it with selectors

const getItems = state => state.items;

function* deserialize( action ) {
    const items = yield select(getItems);
    ....
    yield put({ type: 'DESERIALIZE_COMPLETE' });
}
